This is not possible. I'm assuming for the rest of this answer that the elements you're interested in are <td>s. If so, then you should be aware that the name attribute is not valid for <td> elements.

You will have to create a list of matching elements manually. If you decide to use the name attribute anyway (instead of, say, adding a class in the class attribute), something like the following will work:

var table = document.getElementById(your_table_id);

var tds = table.getElementsByTagName(td);

var matchingTds = [];



for (var i = 0, len = tds.length, td, tdName; i < len; ++i) {

    td = tds[i];

    tdName = td.getAttribute(name);

    if (tdName && tdName.indexOf(tdName_) == 0) {

        matchingTds.push(td);

    }

}
